Dr. David Dao, the passenger who was seriously injured as he was dragged off of an overbooked United Airlines flight, has reached "an amicable settlement" with the carrier, according to his legal team.

According to a Thursday release from the Chicago firm of Corboy & Demetrio, the sides reached a settlement that "includes a provision that the amount remain confidential."

United took a major public relations hit after video of the April 9 incident in Chicago went viral over social media, and the airline industry's practice of overbooking was thrust into the spotlight.

Attorney Thomas Demetrio, however, praised embattled United CEO Oscar Munoz in the release, saying the executive "said he was going to do the right thing, and he has."

The settlement comes as United promised earlier Thursday to increase the limit -- to $10,000 -- on payments to customers who give up seats on overbooked flights, reduce the number of oversold flights and improve employee training. Other airlines have announced new policies related to overbooking, as well.

"Dr. Dao has become the positive unintended champion for the adoption of changes which will certainly help improve the lives of literally millions of travelers," Demetrio said.

"I sincerely hope that all other airlines make similar changes and follow United's lead in helping to improve the passenger flying experience with an emphasis on empathy, patience, respect and dignity."

Dao was asked to leave the plane after commuting crew members boarded at late notice. He refused and was eventually dragged screaming from his seat and down the aisle of the plane as fellow passengers looked on in disbelief -- cell phone videos of the incident went nationwide in hours.

In a news conference shortly after the event, Dao's lawyers said he suffered a concussion, broken nose, injury to the sinuses and lost teeth.
